Trait differential_dataflow::trace::implementations::Update

pub trait Update {
    type Key: Ord + Clone + 'static;
    type Val: Ord + Clone + 'static;
    type Time: Ord + Clone + Lattice + Timestamp;
    type Diff: Ord + Semigroup + 'static;
}

A type that names constituent update types.

Required Associated Types

type Key: Ord + Clone + 'static

Key by which data are grouped.

type Val: Ord + Clone + 'static

Values associated with the key.

type Time: Ord + Clone + Lattice + Timestamp

Time at which updates occur.

type Diff: Ord + Semigroup + 'static

Way in which updates occur.

Object Safety

This trait is not object safe.
